标题[问题] 一题osmotic pressure and Ksp的题目 帮看答案对否.

6. The osmotic pressure of a solution saturated with a salt M3X2 is 2.64 x 10(-
2次方) atm at 25度C.
Calculate Ksp value for M3X2, assuming ideal behavior. (R = 0.08206 L atm/ K
mol)
算法:
0.0264 = 5s x 0.08206 x 298
s = 0.0264 / (5 x 0.08206 x 298)
Ksp = 108s(5次方)
Ksp = 5.068 x 10(-17次方)
这样算答案对吗?请大家帮忙看一下算法有无错误.
